LANVIEW LEDs

PWR

When this green LED is on, it indicates that the SEHI is receiving power.
If this LED is off, it indicates a loss of input power. Check the input
power source (circuit breaker, fuse, etc.). If the proper source power is
present, the problem could be with the SEHI.

CPU

This LED alternates from red to green to during power up. After the boot
is complete, the LED blinks green. A blinking green LED indicates
normal operation. A red LED indicates a faulty processor.

NOTE

Flashing indicates an irregular LED pulse.

Blinking indicates a steady LED pulse.
